Sherry vinegar (Spanish: vinagre de Jerez) is a gourmet wine vinegar made from Sherry. It is produced in the Spanish province of CÃ¡diz and inside the triangular area between the city of Jerez de la Frontera and towns of SanlÃºcar de Barrameda and El Puerto de Santa MarÃa, known as the "sherry triangle". To be called vinagre de Jerez, by law the Sherry vinegar must undergo ageing in American oak for a minimum of six months, can only be aged within the "sherry triangle" and must have a minimum of 7 degrees acidity. Most Sherry vinegars are aged using the same solera system as the Sherry wines and Brandy de Jerez. The production and quality of sherry vinegar is monitored and controlled by the Consejo Regulador and Sherry vinegar has its own DenominaciÃ³n de Origen, which is protected by Spanish and EU law. The only other vinegars with similar protected designation of origin are "Aceto Balsamico Tradizionale" from Modena and Reggio Emilia in Italy and "Condado de Huelva" in Spain Sherry vinegar was originally "discovered" by French chefs. In 2008 France was the largest market for sherry vinegar. Vinaigrette made from sherry vinegar is particularly flavourful and matches well with many foods, not just salads, but steamed asparagus or globe artichoke for example. In Jerez de la Frontera a traditional dish is "RiÃ±ones al Jerez": lambs kidneys with a sauce made from sherry wine and sherry vinegar. The best sherry vinegars have a deep, complex flavour and enhance the flavours in soups, stews, sauces, casseroles and dressings. Use Sherry Vinegar to make the perfect Gazpacho or Salmorejo.
